Benton High School was closed through school unification. The Benton Tigers won the Kansas State High School class B baseball championship in 1957.

Circle Middle School is the home of the Thunderbolts. The school is a part of the Walnut Valley League (WVL). Students from Circle Benton Elementary, Circle Towanda Elementary, Circle Greenwich Elementary, and Circle Oil Hill Elementary attend this school in their seventh and eighth grades. After graduating, the students move onto Circle High School in Towanda.

Circle Middle School used to be a combination of Circle Benton Elementary and Circle Towanda Elementary, which, at the time, were both K-8 schools. Circle Oil Hill Elementary bused their kids over to Circle Towanda Elementary for classes. When the schools became too crowded due to the influx of jobs in nearby Wichita, El Dorado, and Andover, the school board voted to build a middle school in Benton. The project was completed by Summer 2002. Classes began in the fall. The first 8th grade class to go through the middle school graduated in 2007 from Circle High School.
